HSE Crystal - choosing the right capacitor

Hi :) I am doing a project where I need a (relatively) accurate crystal. I have never used special precision crystals but my guess is a normal crystal would do. I would like though to have the best accuracy possible by laying out the PCB and choosing...

Driving 7 segment Display with STM8 - enough current?

Hi again =) ​I have a small project with an STM8 and I was thinking driving my 3-digit 7 segment display directly with the MCU in order to reduce the manufacturing price (I know some of these chips cost only a few cents but if I *can* do it directly ...

An example of STM8L SPI DMA regular buffer exchange between master and slave.

The example from STM8L15x-16x-05x-AL31-L_StdPeriph_Lib doesn't explain the way a regular buffer (i.e. 20 - 30 bytes of data) exchange between two MCUs in master and slave mode. Can anyone explain the steps of configuration on both sides?Now I have ST...

STM8L051 ADC Pin current consumption when HALT

Using STM8L051 ADC PD0, 3.7V~4.2V Li-Po battery, 1M+1M resistor to divde the battery voltage, 100nF capacitor to GND.If set PD0 floating input and halt, total current 40uA, if set PD0 push-pull output LOW, 10uA. But the drawback of output LOW is that...

I have a question regarding TIM1 deadtime configuration on STM8S003F3.

I am working on a project with the STM8S003F3. I need to configure the TIM1 to generate the following digital output signal on PC3:1. Turn PC3 output to High state immediately (<1us) when signal on PC4 input goes Low.2. After PC4 input signal goes Hi...

How to decompile STM8 firmware

Hi, I'm trying to reverse engineering a STM8 firmware. till now I can disassemble the binary firmware to get the assembler code using naken_asm : https://github.com/mikeakohn/naken_asmIs it possible to decompile it ? can anyone point me to some tools...

[SOLVED] Custom board with STM8 - SWIM Pinout?

Hi =) I am designing a custom board with an STM8. I have a couple of STM32 Nucleo and eval board but looking at the schematics the ST-link only seem to have the SWD interface, not the SWIM.I do not have any STM8 board from ST have but I have another ...

When USING IAR to simulate TIM5 of STM8151C8, the event update flag bit (UIF) could not be cleared away, and tim5 would always be interrupted. However, after the program was burned out, the MCU operated normally

从哪�?�以找到stm8s系列的头文件和芯片包 求告知 最好有链接

I am using STM8S001J3 MCU for my application. For the development purpose I am using STM8-SO8-DISCO development board. Suddenly I am not able to program the board.

It shows following error message when I program the board. Please find attached image for this. I am using IAR embedded workbench IDE for my development. Please help me with this as I am facing this issue since two days and not able to crack it.Thank...
